PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell which can suppress projection of fibers, even if it is applied to a fuel battery and operation is continued.SOLUTION: In a polymer fuel cell CE, an anode side diffusion layer 22a contains single fibers CF, and different magnetic poles are formed on an electrode catalyst 21a side and a fuel gas passage 23a side. In a cathode side diffusion layer 22b, different magnetic poles are formed on an electrode catalyst 21b side and an oxidation gas passage 23b side. The anode side diffusion layer 22a and the cathode side diffusion layer 22b are arranged so that the polarity on the electrode catalyst 21a side is identical to the polarity on the electrode catalyst 21b side. |
